| - | Thorndike is the most commonly cited connectionist. Central to his ideas on learning were three laws of learning, which should have accounted for both human and animal learning:(([[http://userwww.sfsu.edu/~foreman/itec800/finalprojects/annie/thorndike%27slaw.html|Foreman, Kim.

| - | Connectionism was at its time considered a general theory of learning for both humans and animals. Thorndike's ideas which could well be applied for learning are the idea that rewards promote learning and that repetition enhances learning. | + | Practical implications of Thorndike's ideas are suggested through his laws of learning: |
| + | |||
| + | * rewards promote learning, but punishments do not lead to learning, | ||
| + | * repetition enhances learning, and | ||
| + | * potential to learn needs to be satisfied. | ||
| In his book on learning of mathematics((Thorndike, E. The Psychology of Arithmetic. New York: Macmillan. 1922.)), Thorndike suggested problems children are expected to solve and learn from should be realistic. For example learning to multiply by three should be learned in context of converting feet to yards. He also emphasizes importance of **repetition** and insists on repetitive practice of basic arithmetic operations. Some of the principles in this book even seem inconsistent with his views on learning: here he refers to learning as meaningful and insightful. Well-learned basic skills enable learning of higher-order skills. | In his book on learning of mathematics((Thorndike, E. The Psychology of Arithmetic.
